California Solar Incentives & Rebates Guide 2026

The federal Investment Tax Credit (ITC) allows California homeowners to deduct 30% of the total cost of a solar energy system from their federal income taxes. For a typical 6kW system costing $16,920 in California, that's a direct tax credit of $5,076. This isn't a deduction — it's a dollar-for-dollar reduction of your tax bill.

The 30% ITC is available through 2032 under the Inflation Reduction Act, then steps down to 26% in 2033 and 22% in 2034. There's no maximum cap on the residential credit. If your tax liability is less than the credit amount, you can roll the remaining credit forward to the next tax year. The system must be installed on your primary or secondary residence, and you must own it (leased systems don't qualify for the homeowner credit).

California does not currently offer a state-level solar tax credit. However, California homeowners still benefit from the substantial 30% federal ITC, worth $5,076 on a typical 6kW system. Additionally, SGIP (Self-Generation Incentive Program) for batteries; SOMAH for affordable housing. Even without a state credit, solar is economically attractive in California with electricity rates averaging 32.54¢/kWh — well above the national average.

Great news for California homeowners: Solar energy systems are exempt from property tax assessments. 100% property tax exemption through Dec 31, 2026 Studies show solar adds 3-4% to home values. For a $300,000 home, that's roughly $12,000 in added value — and with California's property tax exemption, you save approximately $132 per year in property taxes you'd otherwise owe on that increased value.

California does not currently exempt solar equipment from state sales tax. This means you'll pay the applicable sales tax on your solar system purchase. However, the 30% federal ITC and other available incentives more than compensate for this cost in most cases.

Net metering policy: Net Billing (Reduced Rate). NEM 3.0 (Net Billing Tariff) since April 2023; export credits based on avoided cost by time of day, significantly lower than retail

Under California's net billing policy, excess solar energy sent to the grid is credited at a rate lower than the retail price. This means it's important to maximize self-consumption — use major appliances during peak solar hours and consider adding battery storage to capture excess generation for evening use.

Utility rebates and state programs can change frequently. We recommend checking with your local utility and the Database of State Incentives for Renewables & Efficiency (DSIRE) for the most current programs available in your area.

California has a mandatory Renewable Portfolio Standard (RPS) target of 60% by 2030, 100% clean energy by 2045. This legally binding target drives continued investment in renewable energy infrastructure and often supports solar-friendly policies like net metering and SREC programs. A strong RPS is generally good news for solar homeowners, as it creates market demand for renewable energy and helps maintain favorable solar policies.
